Bugfix #13119 fixed the splat bug in Style/MapIntoArray, but it also limited the types of offenses the cop recognized. For example,

dest = []
arr.each { |e| dest << [1, e] }
arr.each { |e| dest << true }
arr.each { |e| dest << (cond? ? 1 : e) }

and several others are no longer detected as of 1.66.1

This PR restores the original cop behavior while preserving the splat fix.
